The fast digital integrator has been conceived to face most demanding magnet test requirements with a resolution of 10 ppm, a signal-to-noise ratio of 105 dB at 20 kHz, a time resolution of 50 ns, an offset of 10 ppm, and on-line processing. In this paper, the on-field achievements of the fast digital integrator are assessed by a specific measurement(More)
A framework for easily developing software for measurement and test applications under highly and fast-varying requirements is proposed. The framework allows the software quality, in terms of flexibility, usability, and maintainability, to be maximized. Furthermore, the development effort is reduced and finalized, by relieving the test engineer of(More)
− A technique for generating user interfaces in software frameworks for automatic measurement systems is proposed. The user interface is separated from the application logic with the aim of enhancing flexibility and reusability of the software. A Model-View-Interactor paradigm focuses on the " interaction " between the automatic measurement system,(More)
The rotating coil technique is extensively used in high-precision measurements for accelerator magnet testing. One of most relevant error sources is the drift arising from the integrator offset. In this paper, a correction algorithm for the offset drift in digital integrators is presented. Preliminary experimental results for the measurement correction of(More)
—A Petri net (PN)-based approach to software synchronization in automatic measurement systems is proposed. Tasks are synchronized by means of a PN modeling an execution graph, where nodes represent tasks and arrows among nodes point out time succession among the corresponding tasks. This allows software synchronization to be abstracted above the code level(More)
Synchrotron particle accelerators are mainly composed of magnets. Long dipole magnets are employed to bend and to contain the beam within a circular trajectory. Their field quality is usually tested by arrays of rotating coils. Typically the measurements must be affected by low uncertainty (+10-4) and the calibration of the sensing coils, in terms of(More)
